EUGENE PRINGIJE, OF GLOVERSVILLE, NE\V YORK.

BUTTON-SETTING MACHINE.

. JPECIPICATION forming part. of Letters Patent No. 338,776. dated March30, 1886.

(No model.)

To aZZ whom, it may concern:

Be it known that I, EUGENE PRINGLE, a resident of Gloversville, in thecounty of Fulton and State of New York, have invented. certain new anduseful Improvements in But ton'Setting Machines; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, that will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in button-setting machines adaptedto attach buttons to garments, and especially sectional buttons, whereinone section provided with a post or stud is attached to one fly of agarmentopening, and the other section provided with a hollow rivet ortube adapted to receive said post is attached to the other garment-fly.

Figure 1 of the drawings is a side elevation of one side of my improvedmachine with jaws closed. Fig. 2 isa side elevation showing the sideopposite to that shown in Fig. 1, with the jaws open. Fig. 3 is a planview of the face of anvil 9. Fig. 4 is a central vertical section ofsame. Fig. 5 is a central vertical section of the anvil and abutton-section, fabric, and washer resting thereon in position to be set(Enlarged scale.) Fig. 6 is a front elevation of the machine. Fig. 7 isa vertical section of the upper jaw and perforated swage and plunger.Fig. 8 is a side elevation of the post-section of a button. Fig. 9 is aplan view of a washer. Fig. 10 is a vertical central section of thepost-section of a button attached to the fabric. Fig. 11 is a view inelevation of the slotted tube.

A is the bed-plate or frame of the machine, which supports the anvil O.The upper member, 13, is fulcrumed upon the frame by pivot A, andprovided with lever B. The ends of lever B and frame A are connected bya toggle-joint formed of links I and J. The knee of this joint isconnected with lever B by an other toggle-joint, made up of the links Hand F. The link F is provided with a swinging lever, G, integraltherewith, or securely fixed thereto. The lever G is provided with aconvenient foot-rest, G, at its lower end, for operating the same, andthrough the compound togglejoint thus formed the lever B and fulcrnmedmember B. By swinging the lever G backward and forward the connectingparts are changed from the position shown in Fig. 1 to thatshown in Fig.2 and back again, from which it will readily appear that great power isobtained without a very extended sweep of lever G, and that gravity,acting through le' Ver G and the connecting parts secured to lo ver B attwo separate points, will restore the parts to the position shown inFig. 2 after they are released from constraint in position shown in Fig.1.

K is an upright supporting the stop K, which may be made of rubber orother elastic material to receive the projecting end L of lever B.

The member B is provided with the swage D,having an opening, D, therein,adapted to receive the rounded end of post m of a buttonsection, such asshown in Fig. 8. The post is provided with a projecting step, 1,extending up a short distance from the upper side of the I base 0,adapted to be swaged down upon a thin washer, 0-, placed thereon afterthe post has been inserted through the fabric to which the same is to beattached, which is the object to be accomplished by the perforated swageD. After the post has been inserted in the fabric and the washeradjusted thereon, the head of the post is inserted in the perforation Dand the swage forced down toward the anvil O by means of the lever Guntil the base of the buttonsection striking the anvil forces theprojecting step t against the swage, which upsets the edges upon thewasher o and secures the section upon the fabric, as shown in Fig. 10.

The opening D is provided with a slight enlargement around its mouth, asshown in Fig.

7, which serves to control the movement of the edges of the step whilebeing upset by the swage and give them a uniform and smooth appearance.It also serves to present a ring projecting down below the working-edgeof the swage to push the washer down below the upset edges of the stepwhile they are being upset. As the post at is forced with great pressureinto the opening D, it frequently adheres very firmly to the swage, andIhave provided the plunger a,adapted toslide vertically within theopening in the swage and strike at its upper end the stop E on theupright E when the member B recedes from the anvil, thereby forcing theplunger into the swage and driving the post therefrom and releasing it.

I do not regard the stop E as a necessary element, because the plunger amay be operated by ahammer in the hands of the operator.

To set the other section of the button,I provide another fulcrumed leverconsisting of the member P, fulcrumed at i, and provided with theoperating-lever P, which connects with lever B, as shown in Fig. 6, andwith the setting punch or hammer d, operating in conjunction with theanvil g, which rests upon the bed-plate or frame of the machine. Thesection of the button set by this part of the machine is thebutton-head, and is shown in vertical section in Fig. 5, and is composedof a chambered spring-inclosing shell provided the washer also, as shownin Fig. 5.

with a centrallyprojecting post-receiving tube, a. The tube is slottedtransversely at one side, as shown in Fig. 11, to receive thespring-locking catch 1;. (Shown in Fig. 5.) This catch serves to engagewith the-groove 0 in the post (shown in Fig. 8) to hold the two'3button-sections together when in use. This slot in the tube lessensits power of resisting the force of compression necessarily-applied atthe ends of the tube in setting the buttonhead upon the fabric, and Iprovide the supportn, projecting centrally from the anvilg, as shown,the utility of which will be readily seen upon examination of the methodof attaching the head to the fabric. The head is placed upon the anvilbottom side up, and the fabric upon the head so that the tube u projectsup'thr'ough the same, as shown in Fig. 5. The washer 1",with a centralaperture just fitting the tube, is then laid upon the fabric so that thetube projects up through The lever G is then put in mot-ion, causing themember P of lever P to descend toward the interposed button-head andcarry before it the plate 6, pivoted upon i and actuated and controlledby the spring S, (shown in dotted lines in Fig. 2, coiled around thesetting-punch d until the plate strikes the washer and forces it'downfirmly against the fabric, arresting the movement of the plate. Themember P continues to advance against the yielding spring, thus forcingthe punch (I through an aperture in the plate to contact with'the'projecting end of the tube, which it upsets and bends over upon thesurface of the washer, as shown by dotted lines in Fig. 5, therebyfirmly securing the head to the fabric. Meanwhile the catch 11, restingin the slot of the tube and upon the support n, has held up that side ofthe tubewall and enabled it to withstand the force of compressionemployed in upsettingthe tube upon the washer. The plate e also servedto hold the washer tightly upon the fabric until the tube wasupsetthereon and rises again to the position shown in Fig. 2. Spring S neednot necessarily surround punch d, but may occupy any convenient positionbetween the plate and member P, and may be wholly a controlling-spring,the plate being held down by the hand of the operator through the handleshown by dotted lines in Fig. 2.

My invention is equally applicable to any device in which the swage andpunch or anvils are given a reciprocating motion,whet her they travel infulcru med levers or slidin plungers.

What I claim as new, and desire to secure by Letters Patent, is I 1. Ina button-machine, the combination, with the frame A and lever B, of thelinks-H I J F and the lever G, carrying foot-rest G, as and for thepurpose described.

2. The combination, with the anvil G, ofa perforated swage, D, providedwith an open ing, D, slightly enlarged at the mouth thereof, whereby astep, t, on a post, m, may be swaged, as described.

3. The combination, with the perforated swage D, of the springplunger a.and the stop E on an upright, E, of frame A, as and for the purposespecified.

4. The combination,with lever B andanvil g, of the lever P P, carryingpunch d, asshown and described. y

5. In button-setting machines, the combination,with the anvil 9, havingconcave top and central projection, n, and punch d,of the spring S andhinged plate 6, the latter holed to receive punch, as shown anddescribed.

I11 testimony whereof I-have hereunto set my hand this 27th day ofFebruary, 1885.
